Abstract

Based on a method of measuring tiny deformation by scanningFabry-Perot interferometer, a testing system for piezoelectric constantsis proposed. In this paper, we discuss the measuring principle, themeasuring apparatus, and experimental results for a typical example. Thepiezoelectric constants obtained by this method are in very good agreement with theexperiment data by the IEEE method.
